Available on echograms of ping mode:

Description

Single beam algorithm

1 (Single beam)

An edge detection algorithm that produces 2D regions. Only available if data was collected by cruise scanning.

Note: requires a moving platform.

See: About 2D schools detection.

Cruise scanning algorithm

2, 3, 4 or 5
(Multibeam, H-mode, V-mode or S-mode)

An object detection algorithm that produces 3D regions. Only available if data was collected by cruise scanning.

Note: requires a moving platform.

See: About 3D schools detection and 3D schools detection algorithms.

Instrument scanning algorithm

3 or 4
(H-mode or V-mode)

An object detection algorithm that produces 3D regions. Only available if data was collected by instrument scanning.

Note: partitions the data into frames and you may need to prepare your data for this to succeed.

See: About 3D schools detection and 3D schools detection algorithms.

By ping algorithm

2, 3, 4 or 5
(Multibeam, H-mode, V-mode or S-mode)

An object detection algorithm that produces 3D regions with a specified region width, on a ping by ping basis. Available for specified pings or the displayed ping, for a fixed or moving platform.

See: About 3D schools detection and 3D schools detection algorithms.

Target-locked scanning algorithm

3 or 4
(H-mode or V-mode)

An object detection algorithm that produces 3D regions. Only available if data was collected by target-locked scanning.

Note: requires two variables, one of ping mode 3 (H-mode) and one of ping mode 4 (V-mode).
